To all whomitmay concern:

Be it known that I, FRANKS. INeonDsBY, a citizen of the United States, residing at Pine Lake, in the countycf Oakland. and

Stateof Michigan, have invented a certain new and useful Improvement in :Dump- Cars, of -\VlllCl1:l';l16 lfOllOWlIlgiS a full, clear,

and'exact description, reference being had to the accompanying drawings.

My prior Patent, No. 1,013,552, .issued January 2, 219112, shows andclaims a combined locking and raising mechanism for dump cars, so arranged that oscillations of a lever, which in final position locks the doors, may serve \to raise them. The invention glS there shown as embodied; in a car of the Ingoldsby type, wherein a loadsupporting door :has iprogecting lflOOI beams which may be engaged by hooks on the sides of the car .to hold it in closed position, :the hooks on the two :sides being operated by two leverslrespectively. To .raise the doors, :a longitudinal bodily-.movable bar :is provided on each'side, which .is connected by flexible members with the door and has teeth which may beengaged by a pawl carried by an extension of the main locking lever. A suitable detent pa-wl is also provided, which :may engage :these teeth. Thus oscillations of the main lever may serve to gradually move the longit'u' dinal bar and :pull aup on :the chains to 1 close the door. H a

The present invention is .in the :nature an improvement on-the structureshown in the prior patent referred to, and includes means for preventing undue slack in the chains attached ato theldoors; means for effectively guiding rthe chains; means. ;preventing any rebound of the longitudinal bar; means for .giving Zthe detent ;pawla spring engagement with .the teeth on the bar, when desired, while-enabling it .to vbe idle when the car is ready for discharge; means for insuring the :release of the detent pawl and athe ratchet fpawl when the car is locked; :and, finally, means for protecting the teeth and preventing .them from being stripped when the cards bemgunloaded. All these features will be lhereinafter more fully explained and their esseninvention; Fig. .2is a transversesection of the same, on a zlarger scale; Fig. 3 is an end view of a portion of the car adjacent to .the .right-handside; Fig. 4 is a fragmentary planwadjacent to the end :(lf the car showing the detent pawl and its immediately coacting parts; Fig-5 isa detail in cross sectionshowing the guiding pulley carried by the lower chord; 6 is a detail in longitudinalsection illustrating the bodily movableoperatingbar and chain and the two pulleys which coact with I theibodilymovable bar and support and ,guide .the chain; Figs. 7 to 10 inc'lusiveshow a different arrangement of locking device for the detent pawl; Fig. 7 .is .a gpartial side elevation ofiacar equipped with a locking device for the main operating lever, the

' :Referring to the partsiby numerals, 15 represents theside of a;-.car which .is shown as a plate-girder .having ailower chord 16,

an upper chord 17, .and side stiffeners 19.

20 designates .a central longitudinal ridge member which may be employed. 22 indicates inclined rend floors. Such construction may ireadily divide the car into two or levers 30 the lower ends of which are adapted to engage beneath the projecting ends of the floor beams 27. Each of these hinged levers is pivoted near its lower end as illustrated at 31. The hook portion may conveniently be beveled at its engaging edge 32, and the projecting ends of the floor beams may be hooked. in a plane parallel with the door, as illustrated at 33, so that the side hooks and the floor beamhooks interlock with each other and serve to pull the doors snugly up against the lower chord 16 and at thesame time hold the side of the car against outward bulging.

To hold the hooking levers 30 in their locked position, as well as to release them as a unit, they are all pivoted at their upper ends to a longitudinal link 35 which is connected at its end to the main operating lever 10. This lever is shown as pivoted at 4:1 to

the side of the car, which is suitably reinforced at this point. The movement of the lever 4L0 is limited by the guide iron 45, shown as extending alongside of the path of movement of the lever and secured at one end to the car side and at the other to an inclined end strut 4:7.

It will be seen from the construction de scribed, that when the lever is in the position shown in Fig. 1 the hooks engage beneath the floor beams and support the doors. If, however, the lever be thrown forward 0., toward the right, Fig. 1), the lever hooks will be withdrawn :tromthe floor beams and the door will drop by gravity.

To raise the door or doors, I provide the bodily-movablelongitudinal bar 50, to which are anchored chains 51, of which there may be any desired number and which extend over pulleys 52 and thence downwardly and are secured at their lower ends to the doors;

for example, to the projecting ends of floor beams 27 on the under sides of the doors or to separate attachments 2S fastened to the door. Coacting with the pulleys 52, over which the chains pass, are guide pulleys 5d. here the chain passes across the lower chord of the car I provide a suitable guide, which may be a pulley consisting of a sleeve 55 journaled on the intermediate portion of a U-bolt 56, the legs of which extend upwardly through the outstanding flange of the lower chord and are bolted to it. One or both of the pulleys 52 and 54 which support and guide the chain also support and guide the longitudinal bar 50. To efiect this these pulleys may be provided with flanges 53 at their edges. The end portion of the bar 50 is shown as supported by flanged ulleys 57. The longitudinal bar lies close to t e car side and extends through openings in the stifl'eners, which effectively prevent any displacement of the bar.

It will be seen that a movement of the bar 50 toward the left in Fig. 1, will result in drawing upwardly the depending portions of the chains and thus raising the doors. To

cause this movement of the bar I provide ratchet teeth 60, on its upper face, with which may coact a pawl 61, pivoted at 62 to a lower extension of the main operating lever 10. I provide also a detent pawl 64 which extends transversely of the end of the car and is intermediately pivoted at 65 and stands above the teeth 60 and below an extension or tail 66 on the pawl 61.

When the outer end of the detent pawl 64 is in elevated position, as shown in Fig. 1, it is idle, and it also holds in idle position the feeding or ratchet pawl 61. Therefore, in this position the lever is ready to release the supporting hooks as usual. To enable the pawls, however, to effect the movement of the bar 50, the outer end of the pawl 64 is lowered to-engage the teeth 60, and this releases the feeding pawl 61 so that it may also engage these teeth. Then, an inward shoving 011 theupper end of the lever 40 causes an outward movement of the bar 50. The gain made is held by the detent pawl 64, while the following outward movement of the lever 4.0 carries the pawl 61 inward to obtain a new hold on the operating bar 50 and force it endwise 011 the next stroke of the lever 40.

In order to retain the operating bar 50 normally in its left-hand position (Fig. 1), when the pawls are released from it, and thus take up the slackon the chains, I prefer to mount this bar in a position inclined downwardly toward theoperating end of the car, as shown in Fig. 1. A slight incline in this direction is sufficient to insure the bar remaining in the position shown or to cause it to gravitate into such position if displaced. The bar may conveniently consist of two parallel straps rigidly secured together a suitable distance apart to receive the end link of the chain 51, as shown. in Fig. 6. 58 desi nates rivets connecting thebars, and 59 cistance sleeves, through which some of these rivets pass. The teeth 60 may be provided on a T-shaped block 63 secured in the upwardly opening slot between the strips of the bar and held by rivets.

hen the load is dumped by releasing the doors, the bar 50 is moved rapidly to the right, as the doors drop. Should the upper endsof the chains pass beyond the pulleys 52, they'then ride over pulleys 5st; but 1110- mentum will not carry the bar far beyond the normal open position, for as soonas the bar begins to pull the chains in the other direction the momentum is counteracted by the weight of the door, which the chains would have to raise. The incline of the bar also gives a gravity factor opposing this the bar 50 I- am able. to prevent its displacement and to-keep the chains fromsagging,

and by the use of thedouble pulleys 52, 54,.

.fore, makes a simple and efficient construction to meet the conditions resulting from the quick discharge of a heavy load. The toothed portion of the raising bar may, if desired, be protected by a suitable housing; for example, the Z-bar 69,secured to the side of the end platform and overhanging the bar 50, as shown in Figs. 1, 7 and 11. Thisnot only acts as a housing to protect the toothed portion of the bar, but also acts as a-guide to prevent any undue upward movement of the bar and consequent stripping of the teeth by contact with the pawls when the car is being unloaded.

As stated, the doors are rapidly raised simply oscillating the main operating lever 40, the pawl 64 holding the gain made by the pawl 61. In some installations it is suflicient for the operator to maintain the pawl 64: active by holding his foot on the outer end thereof and pressing it downward or under the innerend and pressing it upward against the action of gravity on the longer inner end 68. For some purposes, however, it is desirable to have the pawl 64;

pressed by a spring'into engagement withthe teeth 60. For such installations I may provide the spring shown in Figsr3-and 4:. This spring is a leaf spring pivoted on a vertical pivot by the pin 71 to a bracket 72 secured to the car. In normal running the sarin is idle bein in the osition shown by'dotted lines in Figs. 3 and 4, and out of contact with the pawl 64. The spring may be retained against accidental displacement from this position by lugs 7 3 on the bracket engaging the edges .of the spring. When, however, it is desired to use the spring itis sprung across one of these lugs and thus occupies a position longitudinal of the car, where it stands between thelugs 74, and extends beneath the pawl 64, as shown in Fig. 1. This will give a spring action to the pawl, so that the i'atchet teeth 60 may readily slide beneath it in moving toward the left, but the pawl will effectively hold the gain made-by engaging that face of the ratchet which is at right angles to the bar. The spring is retained in this postion until [the door is raised.

locked, the spring 70 is returned, manually, or by theoperatofls foot, from beneaththe pawl arm 68, and this pawl is thus released by gravity from the operating bar 50. As the inner end 68 of the pawl 64 drops by gravity, its outer .end raises the tail 66 of the feeding pawl 61, so that both these pawls come into idle position, as shown in n some cases it is desirable to provide means for insuring against the operator forgetting to release the detent pawl before he releases the load, since to release the loadwith the detent pawl in engagement would throw greater strain on the raising mechanism than it is intendedto take. To provideffor this I may arrange an automatic release of the pawls. Itis'customary to provide Ingoldsby cars with a locking dog which may lock the main operating lever 40 against movement, this locking dog being turned :to active position as soon as the doors are raised and locked. By suitably connecting this locking dog with the detent pawl 64 I can insure that pawland the feeding pawlbeing thrown into idle positionas soonas the locking dog is moved into activeposition.

A construction illustrating the operation just mentioned is shown in Figs. 7 to 10 inclusive. Inthese figures 80 indicates a bifure cated bracket mounted on the inclined strut 17 and carryinga dog 81, pivoted between thestandards of the bracket, and adapted to beturned in front of the operating lever 40 "and thus prevent the movement of that lever. This dog is shown as an :L-shaped bar higher standard82 ofthe bracket has a hole which may aline with a corresponding hole 84 in. the extension 85 of the dog-when the dog is in locking position.

inner extension (38 of the pawl 64. The

other -end of the lever 87.lies alongside of the end of the carside. -When the inner'end of the lever 87 is pulledupwardly by hand,

it raisesthe inner end of the detent pawl and puts the spring88 under tension. To hold the lever 87 in this position its: outer end passesbeneathaJcatch 90, which is pivoted to a bracket 91 secured to the inclined strut 47. Iconnect this catch by a chain 93 to the arm 85 01 the locking dog. The result of the construction described is that when this dog is turned to active ;po-.

pivoted adjacent to itsangleat 83. The e When these 'holes are alined the dog may be prevented sition, to lock the lever at the end of the raising operation, shown in full lines in Figs. 81(), the pull on the chain 93 swings the catch 90 to release the lever 87. This lever and the detent pawl accordingly drop by gravity into the position shown in full lines in Fig, 8, thus entirely releasing the raising bar. Before the load can be dumped, however, the locking dog 81 must be turned back away from the lever 40, into the position shown in broken lines in Fig. 8. In doing this, the catch 90 drops into active position (shown in broken lines in Fig. 10), so that as soon as the load has been dumped it is possible to swing the lever 87 on its pivot and latch its outer end beneath the catch, thus putting the detent pawl in active position and holding it there under spring tension. This same movement releases the pawl 61 so that the mechanism is in position for action to engage and draw back on the bar 50, which by the dropping of the load has been carried to the right.

It will be seenfrom the above that as soon as the oscillations of the operating lever ll) have raised the doors, and they are locked by the final backward movement of the lever 40, this lever may then be itself locked by positioning the locking dog illus-- trated in Figs. 7 to 10, this positioning, as explained, insuring the release of both the detent pawl and the feeding pawl. 4
